SPOKE-BENDING MACHINE.

SPECIFICATION forming part of Letters Patent No. 500,383, dated June 27,1893.

Application filed February 13, 1893. Serial No. 462,126. (No model.)

To all whom it may concern.-

Be it known that I, PETER GENDRON, a citizen of the United States,residing at Toledo, in the county of Lucas and State of Ohio, haveinvented certain new and useful Improvements in Spoke-Bending Machines,of which the following is a specification, reference being had thereinto the accompanying drawings.

The invention consists in the peculiar construction and arrangement of amachine designed to bend a piece of wire or other metal strip intoproper shape to form two spokes of a metallic wheel, with a properbearing for the hub.

The invention further consists in the peculiar construction, arrangementand combination of the various parts, all as more fully hereinafterdescribed.

In the drawings, Figure 1 is a side elevation of the machine. Fig. 2 isa front elevation of the shaping wheels. Fig. 3 is a section of one ofthe forming wheels. Fig. 4 is an elevation of the spoke formed.

A is the base.

B is a curved standard, having a vertical guide bearing 0 at the front,in which the head D is adjustably secured by means of a screw E. Thishead is bifurcated at its lower end and carries in the bifurcation theforming wheel F. This wheel has beveled edges G and a concave peripheralface H.

I is a wheel, secured to the shaft J, journaled in brackets K on thebase A, and provided with any suitable means for driving it. I haveshown a pinion L to which motion may be communicated from any desiredsource of This wheel has the peripheral flanges M projecting from eachedge, and provided with a series of notches N. Between the flanges thewheel is provided with the convex face 0 and inclined faces P whichextend from the bottom of the convex portion up into the notches, asplainly-shown in Fig. 3.

P is an inclined guide in the rear of the forming wheels.

The parts being thus constructed and motion communicated to the wheel I,through the mechanism described, if a number of pieces of wire are laidupon the inclined guide P, they will be fed by gravity to the lowerendthereof, and as the wheel I turns and presents one of its notches towardthe inclined guide, one of the wires will fall into the notch and becarried with the wheel in its rotation. As soon as it strikes theforming wheel F, it will be bent centrally and shaped between theWheels, as shown in Fig. 2, being carried on by the rotation of thewheel to the opposite side where it will fall off and be caught upon thearm Q from which it may be taken when desired. The spoke thus formed isshown in Fig. 4, the two arms a 19 forming two spokes of the wheel andthe bent portion 0 forming the central bearing for engaging with thehub. With this machine it is evident that all thatis necessary is tofeed the wires upon the inclined guide P. Itis obvious that these wheelsmay be modified as desired to form different bends in the wire, and I donot wish to limit myself to the precise form shown.

The essence of my invention consists as I understand it in theintermeshing forming wheels or dies, one of which is notched toantomatically feed the wires between the two.

WVhat I claim as my invention is- 1. In a metal bending machine, thecombination of a wheel, having peripheral notched flanges, means forrotating said wheel, and a second wheel having a complementary interengaging rim, substantially as described.

2. In a metal bending machine, the combination of a wheel havingperipheral notched marginal flanges, and shaping bearings and dies atthe notches, means for rotating said wheel and a second wheel having arim provided with complementary bearings journaled above the flangedwheel and engaging with its rim between the flanges, substantially asdescribed.

In testimony whereof I affix my signature in presence of two witnesses.

PETER GENDRON.
